TOMZN  SPD Surge Protective Device is intended to protect residential buildings from electrical surges caused by lightning strikes or other power disturbances. It features a 3P+N configuration, which is suitable for three-phase electrical systems with a neutral conductor. The surge current rating indicates the amount of surge current the device can handle before it activates to divert the excess energy away from the protected equipment. The voltage rating specifies the nominal and maximum operating voltages at which the SPD can provide protection.

Features:

• Surge Protection: SPDs divert excessive voltage and current away from connected equipment, limiting the transient voltage to a safe level.
• Voltage Rating: Specifies the maximum voltage the SPD can handle and protect against.
• Surge Current Rating: Indicates the maximum surge current the SPD can absorb without compromising its functionality.
• Configuration: AC 3P+N refers to a three-phase system with a neutral conductor.
• Lightning Protection: SPDs are designed to protect against lightning-induced surges, shielding equipment from lightning strikes and electrical discharges.
• Low-Voltage Protection: SPDs safeguard low-voltage equipment and circuits, preventing damage caused by voltage surges.

Specifications:

• Surge Current Rating: Typically ranges from 20kA to 40kA for normal operation and can handle higher surges up to 30kA to 60kA.
• Voltage Rating: Typically rated at 385V as the nominal voltage and 420V as the maximum continuous operating voltage.
• Construction: SPDs are built with robust components and protective elements like metal oxide varistors (MOVs), gas discharge tubes (GDTs), or silicon avalanche diodes (SADs) to provide surge protection.
